Zinc selenocyanates

In the former study, at 298.15 K and 1 M NaC104, potentiometric (zinc amalgam electrode) titration data were used to conclude that two mononuclear complexes were formed  

The corresponding equilibrium constants were evaluated from a numerical minimisation of the function 2( caic - obs) with the result  

These constants have been extrapolated to standard conditions by SIT using the As values suggested in [97BAH/PAR] in Appendix A to the selected values

Zinc Selenocyanate may be obtained by dissolving either the metal or its oxide in selenocyanie acid. It forms groups of prismatic needles, which are not deliquescent.4 By the action of selenium on a solution of zinc cyanide in liquid ammonia, the compound Zn(CNSe)a. 4NIT8 has been obtained.5 Similar compounds of magnesium and aluminium have also been described. 

Complexes with pyridine JV-oxide of zinc thiocyanate and selenocyanate of the stoichiometry ZnLsX2 (X = SCN, SeCN) have been reported.1066 IR evidence shows that they are best formulated as [ZnL6]2+[ZnX4f. ... 

There are several other methods to reduce diselenides, selenocyanates, and elemental selenium. For example, sodium hydroxymethanesulfinate (rongalite) [26], carbon monoxide [27a], zinc powder [27b],hypophosphorous acid (H3PO2) [28], and sodium hydroxide (NaOH) under phase-transfer conditions [29] have been used to prepare nucleophilic selenium species.
